About this resource
What it does
WhyNotWin11 checks a PC against common Windows 11 readiness criteria and explains which requirement, such as TPM, Secure Boot, processor, storage, or memory, is preventing a normal upgrade path.
How to interpret it
It is a diagnostic report, not an approval from Microsoft and not a tool for bypassing requirements. Confirm any result against Microsoft's current Windows 11 specifications and the PC maker's firmware documentation.
Good next steps
If a requirement is reported as missing, check whether it is disabled in UEFI/BIOS before assuming the hardware cannot support Windows 11. Avoid unsupported-installation workarounds on a device that needs reliable updates and support.
